In order to meet extreme environmental conditions and very high pressure applications, including space limitations, PROCONTROL can specifically engineer unique customized actuators, in order to meet even the more demanding customer requirement. Larger diameter and high pressure class application gate & globe valves generate incredibly high operational thrust forces in service.

In order to meet these requirements and contain the overall dimensions of the actuators, PROCONTROL has specifically engineered a compact high thrust output multi-spring design: heavy duty construction, cylinder assembly which contains multiple helical spring packs. Fast operation is performed by PROCONTROL bespoke integral quick exhaust valve complete with integrated damper device, which enables an ultra high pneumatic or hydraulic flow discharge across 85% of the actuators stroke, after which the damper system is engaged to slow down the kinetic energy as the valve starts reseating, thus avoiding potential shaft torsional stress and damage to the valve seating elements. the bespoke device is fitted with a dedicated flow regulator which allows fine tuning adjustment of the end stroke seating speed. ultra compact.
